Have been playing with this off and on for over a year. The combo 1968 396/325hp big block, 1228747 ecm 2" tbi with 80# injectors. solid 15 psi fuel pressure. Have the truck running ok without a cel at idle and about to 50% throttle and 2600-2700 rpm then goes lean and backfires. Have a wideband o2 wiith af ratio gauge (separate from normal o2) mounted about 6" down from exhaust port. On the fuel map from dead center down and to the right the fuel is maxxed out at 99+. Tried another complete 2" bb tbi with known good 80# injectors and same thing. Dave at Moates said to adjust the BPW in the VE table. Don't seem to be able to locate this. Found bpw vs coolant temp? Could use a little help. When I get this one going I have another to do also with similar setup. Anyone close to Omaha?
